Application ined November 13, 1911. serial-No. 659,905;

To all whom 'it may concern:

Be it known that 4I, CrrARLns Haines,

The. objects of the invention are to gen` erally improve the construction of such oulverts and to provide a means for connecting the sections which is integral with such sections and is simple, strong and durable and by which a plurality of such sections can be easily and quickly united to form a subst-antial culvert for practical use. These objects, together with other objects which will be apparent to those skilled in the art may be attained by the construction illustrated in the accompanying drawings, although the invention may be embodied in other forms, the construction illustrated being chosen by way of example.

In the drawings, Figure l is a perspective view of a culvert embodying my invention, one of the sections being removed to further disclose t-he construction. Fig. 2 is an enlarged, fragmentary, transverse sectional view through one of the lateral seams, showing the flanges unfastened. Fig. 3 is a similar view showing the flanges fastened by the integral lugs.

Throughout the several views similar reference numerals indicate similar part-s.

The complementary sections composing the culvert are indicated in the drawings by the numerals 1 and 2 and may be either plain or corrugated or partly plain and partly corrugated. Circumferentially corrugated sections are commonly preferred and I have so illustrated them. At its lateral seam edges each section is provided with integral, outwardly extending side flanges 3, along the marginal edges of which are the integral, spaced fastening lugs 4C disposed at right angles to said flanges and directed toward the complementary section. Said flanges and lugs are preferably formed plain as shown in the drawings, although they may be corrugated if preferred, as will be understood by those skilled in the art.

In arranging the sections to form a complete culvert any number of such sections may be employed to produce the desired circumference, but usually two sections only areneeessary, preferably arranged as the lower sections 2 and upper sections 1 in the drawing. It will be noted that the flanges Vof the complementary sections abut, the

flanges of the upper sections resting on the flanges of the lower sections.

The lugs 4t of each section are arranged between the similar, adjacent, spaced, oppositely disposed lugs ofv the complementary Y sect-ion, the lugs of each section thus extending beyond the flanges of the other section and being adapted to be bent over said fianges to firmly connect. the sections together. For the purpose of bending the lugs 4t few and simple tools only are necessary, a hammer or a large pair of pliers may be used in the manner well known to those skilled in the art, it being only necessary that the oppositely disposed lugs as in Fig. 2 be folded over and bent down upon the flanges as shown in Fig. 8. The lugs of the upper sections being interposed between the lugs of the lower sections, relative endwise movement of the sections will be prevented and the lugs being of substantially the same width as the spaces between adjacent lugs, the flanges 3 of the complementary sections will be engaged by the connecting means for substantially their entire length, thus producing a connection of uniform strength.

Vhen the sections are provided with circumferential corrugations, as shown in the drawings, longitudinally adjacent sections should be endwise-overlapped for at least one corrugation and joints between adjacent upper sections should be arranged intermediate the joints between adjacent lower sections producing the well known breakjoint construction.

Attention should be called to the fact that in using a culvert of my invented construction no loose or independent fastening means are necessary so that there is no possibility of losing said fastening means during transportation. The sections in themselves include the fastening means and when put together and the lugs folded over the flanges a substantial, durable and thoroughly efficient culvert is produced.

I claim- Y l. A culvert comprising complementary sections having seam flanges provided With interjacent ylugs folded over said flanges for fastening the sections together.

2. A culvert comprising complementary sections having seam flanges provided with integral, o'ppositely disposed, interjacent lugs vlfolded over said flanges for fastening A y the sections together.

Avl0

3. A culvert comprising complementary sections having outstanding seam flanges provided with oppositely, disposed interjacent lugs folded over said flanges for fastening the sections together.

4l. A culvert comprising complementary sections having outstanding, abutting seam flanges provided at their marginal edges With integral, oppositely, disposed interjaw cent lugs folded over said flanges for fastening said sections together.
